Application filed February 14, #120.V Serial No. 358,646.

To @ZZ whom t may concern.'

Be it known that I, PATRICK WELSH, a citizen of the United States, and a resident of Morristown, county of Morris, and State of N ew Jersey, have invented certain new and useful Improvements in Bolts for Doors, of which the following is a specilication.

This invention relates to an improved bolt for doors, and is particularly adapted for doors such as garage doors, where the door swings outward to a considerable eX- tent and sloping ground makes it diiicult to hold the door open. In garages it very often happens that the door, usually of large surface, unless securely held is blown by the wind or swings, due to an uneven setting of the door frame, toward a closed position, and in this way a car standing in or passing through the door-way is apt to be, damaged.

My invention relates to a bolt which fastens the door shut by having the bottom end of the bolt seated in a socket in the floor, and, also holds the door open by being adapted to be moved a material distance below the bottom edge of the door, so that even if the ground falls away or slopes downward from the edge of the garage or other building, the bolt can still be moved down to a point where it engages the ground and thus securely holds the door in its open position.

The bolt is also constructed so that when it is held raised outI of locking position it must be swung to a position where it is not apt to be engaged, so that its pointed end can not injure a person or tear any clothing, the bolt having off set portions at the top and bottom, so that when in locking position these portions are both lying against the door in a plane substantially parallel to the door and closely adjacent thereto.

The invention is illustrated in the accompanying drawing, in which Figure l is a.

perspective view of a corner of a structure with the door open, the bolt being shown as holding the door in its open position, and being further illustrated, in dotted outline, in its raised or inoperative position, and Fig. 2 is a section on line 2 in Fig. 1.

In the drawing I have shown a structure 10, which will be described, for the purpose of clearly'understanding the invention, as

a garage, and the door 11 is shown swung to its open position, these doors being usually provided at the top with an ordinary latch 12 so that both the top and bottom of the door can be securely locked when closed, this latch 19, however, not being essential. My improved lock consists of a bolt 13, which is mounted so that it can slide vertically and also can be rotated horizontally. F or this purpose I provide bearings 14 Vand 15, the upper bearing lbeing disposed so that any obstruction on the bolt above the bearing is normally a considerable distance therefrom, so that the bolt can be swung to a position where its bottom end is considerably below the bottom edge of the door.

The bolt has an off-set portion 16 at the bottom, which is preferably of crank-like form so that the bottom end 17, 4which is preferably pointed,as at 18, can be swung so that it is below and in front of the door, and when forced into the ground it has a bracing action which prevents any movement of the door toward a closed position and it can not become loosened. y

The top end of the bolt is oE-set, as at 19, which is substantially in the same plane as the off-set portion 16. When the door is opened to the position it is desired to have it occupy, the bolt is forced down by means of the off-set portion 19, which forms a handle, and the point 18 can be driven into the ground to the desired extent, and when the door is to be released the bolt is slid upward by pulling upward on the handle 19, and is held in raised position by catching the off-set portion 19 over a suitable projection, such as the hook 20. In order to catch the olf-set portion over the hook the off-set portion must be swung against the door, and this manipulation of the bolt causes the bottom off-set portion, that is, the pointed end 18, to be swung close to the door and'sub-V stantially parallel thereto, the pointed end 18 thus being protected and any danger ofV injury by avoided.

The bolt is also used for holding and locking the door when it is shut, the socket 21 being provided in the Hoor or door frame of the garage, this socket being formed of a length of engagement with the point is by a distance equal to the amount of olf-set metal pipe and being removed from the normal closed position of the door of the bottom end of the bolt, so that when the door is shut the end 18 Will be seated in the socket 21.

I claim:

A door fastening comprising a bolt of the bolt and Y f thus hold the bolt in raised positionrWith the pointed end of the bolt above the bottom of the door, both off-set ends when thusy raised being held a plane substantially parallel with and against the door, the elements being disposed near the edge of Y. thedoor, but spaced therefrom so that the o-set parts aie Within the edge of the door When the bolt is in its iaised position.

In testimony that' 1 claim the foregoing, l have hereto set my hand, thislOth day of February, 1920.
